Excel, Word, or PowerPoint won't open the file? This tool opens the OOXML package in the browser, lists concrete defects, and fixes the ones you select. The file stays local.
Repairs run fully in the browser. The file is opened as a ZIP/OOXML package and individual XML parts are normalized.
Typical defects: invalid control characters (e.g. 0x1A in a sheet name), bare & characters, missing [Content_Types].xml, orphan relationship entries, or corrupt sharedStrings.xml.
For pure privacy cleanup (metadata, macros), the Office Scrubber is the right tool.
Inspect DOCX, XLSX, and PPTX files locally for metadata, macros, external links, and embedded content.
Convert Office documents to PDF locally with LibreOffice WASM.
Inspect PDFs locally for hidden content, active elements, and potential risks, then download a cleaned copy when needed.
